- CAR-BODY.

1 Application filed June 26, 1914. Serial No. 847,383.

To all whom it may concern Be it known that I, FRANK E. PIXLEY, acitizen of the United States, residing at 922%} Selby avenue, St. Paul,in the county of Ramsey and State of Minnesota, have invented a new anduseful Improvement in Car- Bodies, of which the following is aspecification.

The object of this invention is to minimize the crushing effect in cars,in the event of a sudden blow or impact as in a collision, and thusreduce fatalities in railway wrecks.

To this end my invention consists in mounting a car body on anunderframing, so that in case of the sudden impact of collision, the carbody will shift its position and swing laterally on the underframing,and thus minimize the blow or impact upon the car body and itsoccupants.

In the accompanying drawing, forming part of this specification, Figure1 is a plan view representing the outline of the car body andunderframing, which is adapted to sup port the car body; Fig. 2 is asection on the line XX of Fig. 1; Fig. 3 is a side elevation of a.detail, showing the portions of two adjacent coaches which are shown inoutline in Fig. 1, and Fig. t is a section on line YY of Fig. 1,illustrating the construction of the guide below an end of thecar body,

and of the frangible pin.

In the drawing, the car body A is illustrated with a floor 2 and an endtelescopic vestibule 3, which is adapted to be connected to an adjacenttelescopic vestibule 1 on the end .of an adjoining car body such as 5.The adjacent ends of said telescopic vestibules are inclined at anoblique angle to a longitudinal center line through the car bodies,whereby adjacent car bodies may move freely apart laterally at theirends in case of a collision. The car body such as A is provided with adownwardly extending and centrally disposed king pin 6, which is securedto the floor 2 such as by rivets 7 passing through a flange 8, which isformed integral with the shank of the king pin. This king pin passesdownwardly between the adjacent faces 9 of a pair of parallel channelplates 10, which are secured to the lower surface of a horizontal plate11, and form a guide channel which may also be formed by any suitableconstruction. The plate 11 extends over the area of the top underframingB, which is carried upon the trucks 12 in the usual manner, saidSpecification of Letters Patent.

underframing and trucks being formed as a unit and the car body as aseparate unit, said units being joined by the king pin, so that the carbody may slide longitudinally between the channel plates 10 on theunderframing, and swing on the pin laterally in case of a blow or impactas in a wreck. The king pin 6 is provided with a removable fastener 13,which is secured thereto, such as by bolts 14 over the lower surfaces ofthe ohannel plates. The car body is held on the underframing, so thatsaid parts will maintain their normal relation under a direct pull orpush by means of'a frangible stop C, which is in the form of a pin madeof wood or other suitable frangible material, passing downwardly throughthe floor of the car body and the plate 11 of the underframing. In orderto swing the car body on its king pin laterally in case of a sudden'blowor impact as in a railway wreck a guide 15 is mounted on the undersideof floor 2 of the car body near its end, and depends into a channel 16formed in said floor. The channel 16 has two branches extendingdiagonally from one side of the longitudinal center line of the carbody, one branch being directed forwardly and the other rearwardly,whereby in case of a sudden longitudinal impact against the car body orunderframing sufficient to break the frangible stop C, the guide 15 willfollow in the channel groove 16, either in a forward or backwarddirection, according to which end of the body or framing the force isdelivered and thus slide and swing the car body on its pivot 6longitudinally and laterally, and minimize the j ar upon the car bodyand its occupants.

The length of the channel formed by the channel plates 10 is sufficientto allow the car body to swing with its guide 15 to one side away fromthe guide channel 16, whereupon the car body and the underframing willcontinue to slide longitudinally apart, bearing surfaces 18 in the formof strips secured to the floor of the body such as by bolts 19 beingprovided for imparting an even motion to the car body when it moves uponthe underframing. The ends of the channel formed by the channel plates10 are closed by plates 20 which serve to limit the longitudinal motionof the car body on the underframing. It will be noted that the frangiblestop 0, guide pin 15 and channel 16 for said pin may be duplicated oneach end of the car-body and underfnaming, only one end of a car bodyand ui'iderframing being illustrated in the drawings.

With a car constructedizasidescribdit:is

obvious that upon a sudden impact against either of the ends of the carbody or underframing, the body Will be caused to move longitudinallyandlaterally upon a diagonal line and also swing about to direct.theiimpact or colliding force away from the car body and the passengers2qtl-ierein. {This movement vbeing nfacilitated why 7 the ,pre-
